arm64: dts: ti: k3-j784s4-evm: Assign only lanes 0 and 1 to PCIe1

Currently PCIe1 is setup to use SERDES0 lanes 0 thru 3, and USB0 is
setup to use SERDES0 lane 3 as well.

This overlap in lanes causes the following reset related lane splat:

    [    4.846577] cdns-torrent-phy 5060000.serdes: phy@0: failed to get reset

Let's limit the PCIe1 SERDES0 lanes to 0 and 1 to avoid overlap here.
This works since PCIe1 operates in x2 mode and doesn't need 4 SERDES0
lanes.
